Introduction
Radel R-5800 is a high melt flow grade of Radel polyphenylsulfone (PPSU). It is especially well-suited for parts requiring long flow length with thin walls. Radel resins offer exceptional hydrolytic stability and toughness superior to other commercially-available, high-temperature engineering resins. They also offer high deflection temperatures and outstanding resistance to environmental stress cracking. Radel polymers are inherently flame retardant, provide excellent thermal stability and possess good electrical properties.
